Let's divide 8021713 by 427
The aim is to understand the frequency of 427 in 8021713.

Step 1:
If we divide 8 by 427, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 427

Step 2:
427 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (2) from the dividend, attach it to 80 and continue: 802 / 427

Let's proceed to step 3:
802 divided by 427 is 1 with a remainder of 375.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 427 from 802 to get 375.
Include the next digit (1) from the dividend after 375, then repeat: 3751 / 427

Let's proceed to step 4:
3751 divided by 427 is 8 with a remainder of 335.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 3416 from 3751, we get 335.
Bring next digit (7) of the dividend behind the 335 and repeat the process: 3357 / 427

On to step 5:
3357 divided by 427 is 7 with a remainder of 368.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
If we subtract 2989 from 3357, we get 368.
Append the next digit (1) from the dividend to 368 and continue with: 3681 / 427

Advancing to step 6:
3681 divided by 427 is 8 with a remainder of 265.
Put 8 as the next digit of the answer. 
Result so far: 1878.0
Subtract 3416 from 3681 to get 265.
Include the next digit (3) from the dividend after 265, then repeat: 2653 / 427

Moving on to step 7:
When dividing 2653 by 427, we get 6 with a remainder of 91.
Record the quotient 6 as the next digit in the result. 
Result so far: 18786.0
If we take 2562 away from 2653, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 8:
The number 427 fits into 910 2 times, leaving a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 18786.2
If we take 854 away from 910, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
The number 427 fits into 560 1 times, leaving a remainder of 133.
The number 1 becomes the next digit in our result. 
Result so far: 18786.21
The remainder is 133 after subtracting 427 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 10:
When dividing 1330 by 427, we get 3 with a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 18786.213
The remainder is 49 after subtracting 1281 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 11:
427 can be fit into 490 1 times, resulting in a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 18786.2131
The remainder is 63 after subtracting 427 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 12:
If we divide 630 by 427, we get 1 and a remainder of 203.
The next digit of our result is 1. 
Result so far: 18786.21311
If we take 427 away from 630, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

The final result is 18786.21311 with a remainder of 0.000203.
